I'm shopping for a new anchor to replace my 22# Bruce this off-season and am wondering how likely a new generation (Rocna or Manson) anchor will get stuck compared to a Bruce or Danforth.  Does the extra holding power mean greater risk of not being able to break it free and losing my investment?  I anchor in mud or sand. 

I plan to upsize from 22# to 35# as many here recommend but don't have a windless.  I tell myself it'll be okay since I have no problem pulling up the 22# anchor today and the difference is less than the weight of two gallons of water.  Any other considerations that may make me reconsider anchor size?

Kyle, You WANT your anchor to get stuck.  The alternative is not good.  In the Anchoring 101 Topics there is a discussion of just this phenomenon.   The new gen anchors will literally pull you off the foredeck when they properly set compred to old style anchors which first drag and the hopefully finally set.  This is a GOOD THING.

However, like all anchors when only vertical pull is applied, they do come up.  Always.

I have had my Rocna since 2007.  Never a problem coming up.  Except when it catches underground telephone cables or other crud its found on the bottom.  Two months ago it was a big bunch of twisted heavy metal - have no idea how it got there, something like from heavy farming fencing.  Go figger...

The investment you are trying to maintain is your boat, not the anchor.  Better holding means more consistent confidence in that priority.

Thanks, Stu.  Your statement about always coming up when vertical pull is applied is the reassurance I'm looking for! 

I'm used to slowly coming to a stop when backing down and watching for awhile before being confident that the anchor is set.  I'm sure the difference with a new anchor will be night and day!
